The dad-to-be, who married Fergie in January 2009, told omg! Yahoo on Feb. 20 that he's "always had an affinity for kids." The actor, who played a dad onscreen in his new film Safe Haven and 2010's Life as We Know It, explained, "There's something about me and kids that just click. I don't know if it's because I am a kid, but it does prepare you whenever you're around them."
